“We stood, gripping the cage in an attempt to stay upright, while the cage circled back and forth and at one point was at a 45-degree angle,” Yonker writes.

“Yann’s regulator had been knocked out of his mouth by the shark, so he retreated to the surface to catch a breath and to tell the crew to bring up the cage.”

After the cage was pulled near the surface they still had to work out how to get out with the shark still stuck inside.

Katie added: “It was nearly impossible to see anything because the shark was blocking much of the exit and visibility was limited by all the air bubbles and blood [from the chum bag] in the water…. I could see the boat, but had no idea how I would get around the shark.”

She eventually made it onto the boat and the and the crew freed the shark by tying rope to its tail.

Katie said: “To be clear, this was in no way a shark attack.

"It was a shark enticed by the scent of tuna, not humans. I suspect (and hope) that this incident prompts some changes in the operations, mainly to the design of the cages so that this cannot happen again."

Last month we told how another great white shark defecated on a group of divers who were filming underwater in the same location.

However, it sounds like this time around it wasn't the shark's bowels that were in danger of letting go.
